JAMES A. MARSH, OF CLEVELAND, OHIO.

VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 232,139, dated September 14, 1880.

Application filed June 18, 1880.

To all whom t may concern Beit known that I, JAMES A. MARSH, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain -new and useful Improvementsin Vapor-Burn ers and I do hereby declare the following to be afnll, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had'to the accompanying drawings, which form part of this specilication.

My invention relates to vapor-burners; and it consists in a peculiarly-shaped burner provided with a central support, said burner provided with one or more lines of continuous perforations upon its outside, and also with one or more perforations on its inner surface, and in parts and combination of parts, as will more fully hereinafter appear.

In the drawings, Figure l is a view, in ele vation, of a burner constructed according to my invention. Fig. 2 is a plan view, and Fig. 3 a vertical sectional view, of the same. Figs. 4 and 5 are detached plan views of the rest employed for the burner. Fig. 6 is adetached vertical sectional view of a modification of a portion of the vaporizing chamber and burner. Fig. 7 is a plan View, in transverse section, of my improved burner. Fig. 8 is a plan view of a modification of the same, and Fig. 9 is a view, in elevation, of the modiiication shown in Fig. S.

In the said drawings, A represents the inlet-pipe, adapted to supply the burner with gasoline. B is the generating-chamber. This generating-chamber may extend up and form the central opening within the circular burner, as shown in Fig. 3; or the central portion may be made solid, as shown in Fig. 6.

O is the burner proper. It is preferably constructed in circular form, having one or more lines ot' continuons perforations upon its outside, from which the vapor which is to be mingled with the air is permitted to escape and where it is burned. If found necessary, this burner O may be supplied with one or more perforations upon its inner surface, so as to permit jets of gas to impinge upon its support D', and from thence communicate heat tothe generating-chamber B.

E is a needle-valve operated by 4means of (No model.)

the screw-shaft E. B' is ashort tube leading up from the vaporizingchamber proper, and terminating just above the needlevalve E. The object of this short tube is to convey vapor to the commingling-chamber G, and is placed at an angle with said comminglingchamber, so as to force the gas and vapor as it escapes through the valve against the upper portion ot' the commingling'chamber G. The commingling-chamber G is connected directly with the burner O, as shown in Figs. l, 2, and 3. This commiugling-chamber Gis open at its bottom to permit any gasoline that may be deposited in the burner O to pass to the drip-cup H. It also has an opening at its end, toward the valve E, for the admissionof the vapor from the valve E, and with it air to mingle with the vapor before it enters the burner C.

H is a drip-cup adapted to receive a sufficient amount of gasoline, which, upon being ignited, will furnish the initial heat for the generation of gas.

In constructing this burnerI prefer to make the lower front portion of the ring-burner, as shown at el, thicker than the samepoint at the opposite side, in order to elevate the opening d', so as to permit any gasoline which may have escaped through the comminglingcham ber G into the burner C to flow back and be caught in the drip-cup H.

Having thus described the construction of my device, its operation is as follows: When it is desired to start the iiame the valve E is opened, the gasoline permitted to escape through the orifice F, from whence it will overliow into the drip-cup H. When a sufficient quantity has been permitted to escape the valve is closed and the gasoline in the drip-cup is lighted. In a moment the gasoline in the vaporizing-chamber B becomes sutliciently heated to vaporize, when the valve E is again opened and the gasoline in the shape of vapor permitted to escape th rough the orifice F. rlhe gas passes from the orifice F readily into the commingli11g-chamber G, andfrom thence into the burner C, carrying with it a suiiicient quantity of air to burn it as it escapes through the perforation in the burner C. In this chamber G, and also in the burner proper, the gas mixes readily with the air srs IOO

2 23ans@ admitted, and passes out through the small perforatio11s,where it may be lighted. By the Y time the gasoline is consumed in thc drip-cup I;I sufficient heat has been generated by the burner C to heat its restD, and through it the vaporizing-chamber B, to continue vaporization.

If it is desired at any time to shut oft' the heat-supply, the valve E may be closed.

llhe pipes A and B are provided with illing a b, which may consist oi" asbestus, line Wire, or other suitable material. f The object of this filling is to regulate automatically the flow of gasoline to the vaporizing-chambcr.

The rest D, heretofore described, is provided with a central projection, D', adapted to .litin the space Within the hollow ring-burner. As shown in Fig. 3, this projection D' may be made hollow, thereby forming aportion of the vaporizing-chamber; or it may be made solid, as .shown in Fig. 6, in which case it will act as a heater-plate.

As a substitute for my support D and projection D', apipe of the same shape as that of the burner may be employed, as shown in Fig. 9. The gasoline passing through this under pipe will come in very close contact with the burner above, and sufficient heat will be generated from the burner to vaporize the gasoline in this support.

1. In a vapor-burner, the combination-of a comminglingchamber, G, burner C, and rest or support D, substantially as and for the purpose shown.

2. In a vaporburner, the combination, with the commingling-chamber G, having its end and bottom open, of the burner C, vaporizingchamber B, and drip-cup H, substantially as and for the purposes shown. if

3. In a vaporburner,the combination, with the circular hollow ring-burner C, of the support D, provided with the projection D', substantially as and for the purpose shown.

In testimony whereof I have signed my name to this specificationin the presence of two subscribin g witnesses.
